Organic Liming Materials
Liming is important to agricultural soils as the addition of lime promotes crop productivity by helping plants absorb essential nutrients for proper growth. A decrease in soil pH, know as soil acidification, is a natural process that is accelerated by crop production practices, especially the use of nitrogen (N) fertilizers and heavy tillage. Soils with low pH levels, below 5.0, contain higher levels of available aluminum and manganese that can become toxic to plants which may inhibit growth and greatly reduce yields.
The purpose of liming your soil is to help increase the pH of the soil thus aiding in the uptake of nutrients and maximizing plant growth and crop yield.
Our selection of liming materials include:
Benefits of liming your crop:
- Lime supplies calcium to the soil and reduces the acidity (pH)
- Improves soil structure by stabilizing soil nutrients, which can help reduce soil erosion
- Reduces the availability of aluminum and manganese
- Increases the availability of applied fertilizers
- Increases the amount of available phosphorus, organic nitrogen, sulfur and molybdenum
- Enhances the activity of soil micro-organisms
Liming materials have very limited movement into the soil without incorporation. Tillage increases effectiveness of all lime materials by mixing them into the rooting zone. It is important to think about how the lime will be incorporated into the soil, as well as how deep the soil is being plowed under. If you plow to a depth of 8 inches, it takes twice as much lime compared to a field that is plowed to a depth of 4 inches. Incorporating your liming materials to a depth of 2-4 inches is usually sufficient.
It is important to determine the ideal soil pH for the intend crops that you are growing. Blueberries, strawberries and brambles prefer acidic soils and therefore do not require lime. Most garden crops grow well in soil with a higher pH, between 5.5 and 6.0; however they perform better in a soil with a pH between 6.0 and 6.5 It is important to consider all factors before applying lime, especially soil texture, crop type to be grown, and soil analysis.
If you are applying lime in the fall, it is necessary to incorporate the lime into the soil to prevent surface runoff. Any crop that is pH sensitive should be limed in the fall prior to planting. Spring application is advantageous in areas where permanent sod is maintained, or where there are light applications vs heavy.
